Subject: [PATCH v3 10/15] wifi: ath11k: save max tx power in vdev start response event from firmware
Date:   Tue, 13 Sep 2022 01:15:13 -0400

Save the max tx power received in the vdev start response event from
firmware. A subsequent patch will use this to calculate the final power
value for WMI_VDEV_SET_TPC_POWER_CMDID.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
